Acid Reign Information and Removal.

A RAT is a Remote Administration Tool that gives an attacker the means to manipulate and control a target machine from a remote location over the internet. A RAT gives the attacker full control of the compromised machine and is used for malicious purposes. RATs typically consist of two components: a server application that resides on the target machine and responds to remote commands; a client application that is used by the attacker to control and configure the server applications on compromised machines.

Severe risks are typically installed without user interaction through security exploits, and may allow an attacker to remotely control the infected machine. Such risks may allow the attacker to install additional malware and use the compromised machine to participate in denial of service attacks, spamming, and bot nets, or to transmit sensitive data to a remote server. The malware may be cloaked and not visible to the user. These risks severely compromise the system by lowering security settings, installing 'backdoors,' infecting system files, or spreading to other networked machines.
